INFERNO.COP: Not vouching for this but try this but you have to do it quick since you get a sort of ticket when you press the buy now button, it doesn't just disappear if you navigate away. Anyway go to your history and check out the page you got a hit from. It should end in some sort of code. If you're lucky you can keep going from there.
Might work as long as the game is still on sale but once it vanishes it is probably not possible anymore I guess.
